Bonneville Speedmaster Tail Tidy/harness

Looking to do the exact same setup for my 2018 Triumph Speedmaster. I've already got the new rage license plate holder and the Kellerman Multifunction lights. But wondering how you covered up the hole left from the original tail assembly to make the area watertight? Also could you share a parts list or link for the connectors so I don't have splice the wires? Many thanks!

 

Currently looking to change the Standard indicators 60mm and brake light setup to 40mm Multifunction LED bullets.
They are known as type 3 lights ?
Type 1 being standard 60mm bulbed.

Found there is not a lot of info regarding Triumph part numbers but managed to get there in the end.
Also found Triumph instructions to help with the install
Do also need to have the same LED indicators on the front end

There is a Kit triumph part number A9700592 but seems you may not be able to buy the kit, its more like a parts list containing various key items and additional replacement bolts.

Let me know if you want more info
